It fetches dynamic configuration, opens a mining WebSocket, and allocates Web Workers for computation. - **Trigger:** Browser loading or importing dist/common-js.js - **Impact:** Unconsented CPU use and network participation in a cryptocurrency mining pool. - **Evidence paths:** package.json, dist/common-js.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T12:56:15.416Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated browser cryptominer with remote configuration and worker-based hashing - **Attack narrative:** The sole distributed entrypoint is obfuscated and exposed as the package main and browser CDN artifact. Its code labels the exported runtime XelisMiner, immediately executes browser initialization, fetches configuration from a supplied or embedded URL, creates a WebSocket connection, and spawns Web Workers. This is a concrete browser cryptomining chain hidden behind generic common-js/lodash-like metadata. - **Rationale:** This package is a deceptive, automatically activated browser cryptominer rather than the advertised common utility package. The lack of install hooks does not mitigate the runtime attack. - **Files touched:** dist/common-js.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The published browser entrypoint is a heavily obfuscated artifact, not common utility code., Artifact defines XelisMiner and immediately invokes browser startup., Runtime fetches configurable remote data, opens a WebSocket, and creates multiple Web Workers., Manifest misleadingly labels the package with lodash keywords while shipping only the obfuscated entrypoint. - **Evidence against:** No npm install, preinstall, or postinstall hook is present., No credential or local-file harvesting was confirmed. ## Public findings ### 1.
